Title: Formation of solder bump
Inventor: MIYAMOTO KEIJI
IPC: H01L21/60
Filed: 1979-10-12
Abstract: PURPOSE:To enable integration of solder bump by forming a substance not moistened with solder on a final passivation film before molting the solder film, melting  the solder in this state, and forming a solder bump thereon. CONSTITUTION:A final passivation film 12 of electrode 11 and oxide film is coated on the upper surface of a substrate 10 made of semiconductor thin plate, a wiring layer 13 is formed thereon. The lower layer of the wiring layer is made of titanium layer 14 or the like which is not moistened with solder, and the upper layer is formed of a copper layer 15 of the like which is preferable adherence to the solder. A solder film 17 is formed at the window having the same size as the electrode 11 formed by photoetching. Subsequently, the photoresist film 16 is removed, is heated in the state that the copper layer 15 is removed, and a solder bump 18 is thus formed. Thus, when the solder is heated, the solder flowed to the titanium layer 14 is reduced, and the solder bump can be consequently integrated highly.

Title: Fuel injection quantity control device for internal combustion engine
Inventor: SUGANO YOSHIHITO
IPC: F02D23/00
Filed: 1990-05-21
Abstract: PURPOSE:To enable discrimination whether or not the intake air quantity measured by an air flowmeter is in an erroneous measuring region even at the time of deceleration when a throttle valve is not fully closed by providing a means by which it is detected whether or not the intake air quantity is in the erroneous region of the air flowmeter from the ratio of the calculated measuring value stored by a measured-value storing means at the time before a prescribed time to the measuring value calculated by a calculating means. CONSTITUTION:Since the calculated value of a calculating means 14 is determined by the opening of a throttle valve 12, at the time of deceleration it changes instantaneously with the opening change of the throttle valve 12. At the time of deceleration, since it can be discriminated whether or not the intake air quantity is in the erroneous measuring region of an air flowmeter 11 by whether or not the ratio of the value calculated by the calculating means 14 to the moderated value at the time before deceleration is larger than a prescribed value, it is detected by an erroneous measuring region detecting means 18 from the value of this ratio whether or not the intake air quantity is in the erroneous measuring region. When it is detected that the air quantity is in the erroneous region at the time of deceleration, since the value of intake air quantity being actually measured by the air flowmeter 11 cannot be relied on, the fuel injection time is calculated by the intake air quantity in the steady state.

Inventor: BUREIDEMIA EDOMUNDO BONDEIBEI
IPC: B29C65/16
Filed: 1975-11-04
Abstract: A cylindrical strand with a thermoplastic outer shell (e.g., plastic insulated wire) is bonded along its length to a similar or different cylindrical strand by laser heating. The strands are brought into contact with one another at a contact point. A laser beam of selected power and wavelength is directed at the contact point in a direction approximately parallel to the axis of the strands as the strands are carried past this point. Absorption of the light by the plastic causes melting sufficient to produce bonding. The depth of penetration of the thermal energy into the plastic is controlled by selection of the wavelength of the laser radiation relative to the absorption spectrum of the thermoplastic material. The laser power level is adjusted to control the total energy input in accordance with the strand feed rate.
